Abstract
In a disk drive apparatus, a plurality of data sectors is recorded on a disk. A data sector is designated by a logical block address in accordance with a read command received from a host, and the data is read from the data sector specified by a physical address corresponding to the designated logical block address included in the read command. Predetermined data different from the data read from the designated data sector is sent back to the host in response to information relevant to the physical address included in the read data.
